GAS-BURNER.

Application led June 14, 1918.

To all whom t may concern:

Be it known that I, JOHN A. llna'ron, a citizen of the United States, residing at lWharton, in the county of Morris and State f New Jersey, have invented new and useful Improvements in Gas-Burners, of which the following is a specification.

This invention relates to new and useful improvements in gas burners and the principal object of the invention is to so arrange the parts that an *evenv pressure of the gas is secured in its passage through the intake.

Other objects of the invention reside inthe. peculiar arrangement of the air nozzle within the gas intake, the means for moving said nozzle and intake as an integral part, and the means for controlling the passage of air through the nozzle.

Another object of the invention is to provide a device of this character which is simple and durable in construction, reliable and efHcient in operation and one which can be manufactured and placed upon the market at a minimum cos The invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying` drawings land specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and 1n which Figure l is an elevation of the invention.

Fig. 2 is a plan view.

Fig. 3 is a longitudinal section.

Fig. 4 is a perspective view of the air control shutter and its operating lever.

In these views the gas intake, indicated by the reference numeral 10 is provided with a base 11 which is slidably mounted on a gas chest 12. Said chest is connected with a suitable source of gas supply. As shown, the intake 10 is of elongated form with curved walls. The rear end of said intake is enlarged with the walls converging to the throat 13. Adjacent this throat the intake is provided with an outwardly extending flange 14 to which the flange 15 of the outlet nozzle 16 is bolted. As will be seen the throat opens into the constricted end of said nozzle. 17 indicates the air nozzle located within the gas intake. This nozzle Specification of Letters Patent.

is provided with an enlarged rear end of curved formation and the upper and lower walls converge forwardly to a point a slight distance in rear of the throat 13. The rear and lower walls of the nozzle come together and extend downwardly to form a wedgeshaped partition 1S which divides the gas inlet in the base 11 into two parts 19 and 20. The air nozzle divides the gas intake into two gas conduits 21 and 22 which are connected with the parts 19 and 20. The conduit 2l extends around the rear end ofthe nozzle and above the upper wall thereof to the throat 13 while the conduit 22 is located i large port 23 is formed in each side of the air nozzle and practically embraces the whole side so that these sides of the nozzle are open to the atmosphere. The passage of air through the nozzle is controlled by a balanced shutter which is located adjacent the forwardV end of the air nozzle. This shutter is provided with the trunnions 25 and 26. The trunnion 26 is provided with a square end 27. lVebs 23 are formed in the forward end of the nozzle adjacent the edges thereof and these webs are provided with the sockets 29 in which the trunnions 25 and 2G of the shutter engage. As will be seen the trunnion 26 is of greater length than that 25 and passes through the wall of the gas intake with its square end 27 projecting from said wall. This square end engages a square opening 30 formed in the end'of an operating handle 3l. This handle is provided with a bar 32 suitably secured thereto and having its free end spaced therefrom. 33 is a sector shaped member suitably secured to the intake and engaged by the handle and bar. These parts are so formed as to frictionally engage said member so that the shutter may be adjusted in any desired position in the air nozzle. Openings 34 are formed in the ends of the intake and coininunicate with the gas conduits 21 and 22. These openings are closed by the doors 35 suitably secured in position and adapted to be removed when access is to be had to said conduits.

The rear part of the device is provided with wings 36 having bearings 37 at their ends, in which is journaled a shaft 38. This shaft is provided with a hand wheel 39 and a pinion 40, which is located between the journals. This pinion engages with a stationary rack 41 carried by the chest 12 so that hyv operating the hand Wheel the entire device, consisting of the intake, the air nozzle and the outlet nozzle 16 may be movedtoward and from the 'furnace A. It will be seen that as the device is Withdrawn' from the furnace the gas inlets leading from the chest will be closed, thus shutting oi'- the supply of gas.

An important part of my invention resides in the locationof the air nozzle in relation to the gas intake. Attention is called to the fact that said nozzle islocated in rear of the constricted part or throat of said intake. ln this Way said nozzle Will not aii'ect lthe pressure of the gas by acting as a baii'le,
